The axes of ,;the"

v saw setting element mounted within, axially wall of the socket 11. The drum 7 is fixedly secured to the anvil 3 by a clamping screw 16 which has threaded engagementwith the wall of the opening 10 and seats in the recess 6. When the screw '16 seats in the recess 6 the movement of the anvil 3 relative to the drum 7 is prevented.

The saw set also includes a saw impacting element or hammer and which comprises a pair of angularly disposed arms 17, 18 terminating at their inner ends into an impact receiving head 19 of cylindrical contour and whichhas its lower portion reduced to provide a saw impactinghead or hammer head 19. The arms 17, 1 8 are provided with vertical sockets 20 in proximity to their outer ends and which open at the bottom of the arms. Extending into each socket 20, aswell as depending from an arm is a spring controlled rod 21 formed with a peripheral groove 22 in proximity to its lower end. The rods are anchored to the arms by pins 23 extended through the'f arms and seated in grooves 24 formed in the periphery of the rods near the upper ends thereof. The rods 20 extend into the openings 8 and bear against coiled controlling springs 25 which are'interposed between the inner ends thereof and the disc 2. Carried by the drum 7 are set screws 26 which extend into the grooves 22 for limiting the inward and outward movements of the rods 21 with respect to the drum 7 The springs 25 normally maintain the head in spaced relation with respect to the working face of theanvil 3.

The position of the saw when it is to be acted upon by the set is shown in dotted lines Figure 3 and indicated at 27. The saw seats on the beveled portion 5 of the anvil 3 and also upon the flange 13 of gauge member 12. The gauge member 12 is adjusted for the purpose of adjusting the position of the saw 27 i when it is desired to set the latter. The saw 27 during the setting operation is positioned over the fiatportion 4 of the working face 1 of the anvil 3. 7 i I When a blow is applied to the head 19 it isshifted toward the anvil 3 against the action of the controlling springs 25 and causes the head 19 to impact against the saw.

7 What I claim is 1. A'saw set comprising'a vertical drum, a

of and projecting from the drum, an impact receiving head, a saw impacting head depending from and having its axis forming a continuation of the axis of the impact receiving head and arranged over said element, a pair of oppositely extending angularly disposed arms integral with said impact receiving head and having theirends in alignment, and spring controlled means slidably supported in said drum at spaced points and secured to the'ou'ter ends of said arms.

7 2. A saw set comprising, a handle, a disc secured axially of its inner face to one end of'the handle, an anvil secured to the other face of said disc axially of thelatter, a drum encompassing and of less length than-the anvil andpositioned against the outer face of the disc, means for securing the anvil and drum together, a pair of spring controlled, spaced, aligning rods slidably mounted in, permanently extending from and positioned in proximity to the outer face of the drum, a blow driven saw impacting means arranged over said anvil, and an'gularly disposed means extending in opposite directions from said saw impacting means for connecting the latter with the outer ends of said'rods.

3 Asaw set comprising,a handle, a disc secured axially of its inner face to one end of the handle, an anvil secured to the other face of said disc axially of the latter, a drum encompassing and of less lengththan the anvil and-positioned against the outer face of the disc, means for securing the anvil and drum together, a pair of spring" controlled, spaced, aligning rods slidably mounted in, permanently extendingfrom and positioned in proximity to the outer face of the drum, a blow driven saw impacting means arranged over said anvil, angularly disposed means extending in opposite directions from said saw impacting means for connecting the latter with the outer ends of said rods, said drum having a lengthwise extending. groove in its outer periphery, and an adjustable gauge slidably mounted in said groove. v

4. A saw set comprising a supportformed axially thereof with an anvil, a drum positioned against the support, encompassing and of less length than the anvil,.means for. connecting' the drum to the anvil, a saw impacting element including a pair of angularlydisposedarms opposing the drum and each having a socket opening at thelower face thereof, a pair of reciprocatory, spring controlled rods slidably connected to the drum at spaced points and extending into said sockets, and means for securing the rods to said arms,said element including a dependinghead aligningwithsaid anvil, and

axially thereof, a drum encompassing and detachably connected to said anvil, the latter projecting from the outer end of the drum, and a reciprocatory spring controlled saw impacting element sli-dably connected at spaced points to said drum and having centrally thereof an'impacting head opposing said anvil.

6. A saw set including an anvil, a support carrying and having said anvil arranged axially thereof, a drum encompassing and detachably connected to said anvil, the latter projecting from the outer end of the drum, a reciprocatory spring controlled saw impacting element slidably connected at spaced points to said drum and having centrally thereof an impacting head opposing said anvil, said drum having its outer periphery grooved, and a flanged gauge adjustably mounted in said groove.

In testimony whereof, I aflix my signature hereto.
